Immersion water tank and server cooling system

This application is a National Stage Application of International Application No. PCT/CN2023/077974 filed on Feb. 23, 2023, which claims the benefit of Serial No. 202211108206.7 filed on Sep. 13, 2022 in China, and which applications are incorporated herein by reference. To the extent appropriate, a claim of priority is made to each of the above disclosed applications.

The present disclosure relates to the field of server cooling devices, and in particular, to an immersion water tank. In addition, the present disclosure further relates to a server cooling system comprising the immersion water tank above.

In the current server industry, air-cooled servers are the mainstay and the immersion server market is still in its infancy and not yet widespread.

In the related art, the immersion server is usually provided with a plurality of server nodes placed in a water tank, and the server can be cooled directly by being immersed in a liquid in the water tank, eliminating the need to install a fan in the system. In terms of maintenance, the immersion server is less convenient than traditional air-cooled servers, and when a server node needs to be maintained, the server node must be lifted out of the water tank using an external hoisting device.

However, in the existing immersion server architecture, when a server node is being maintained, the unused space in the water tank is increased as the server node is removed. In this case, the increased space is filled by the working liquid, causing the overall liquid level in the tank to drop. In order to prevent other server nodes that still in operation from experiencing the heat dissipation problems caused by insufficient liquid levels, the liquid in a secondary water tank is usually used to replenish the water tank and restore the liquid level to a predetermined safe level. Such an approach not only allows the working liquid to flow through the unused space without the need for heat dissipation, thereby reducing heat dissipation efficiency, but also requires that an adequate amount of reserve liquid is maintained in the secondary water tank at all times. Due to the current high cost per unit of liquid, the operation and maintenance costs are increased.

Therefore, how to effectively reduce the maintenance cost of the object to be cooled in the immersion water tank is a technical problem to be currently solved by those skilled in the art.

In this embodiment, the immersion water tank comprises:

100 100 It should be noted that the cooling unitis preferably a server, that is, the immersion water tank is preferably used as an immersion water tank for the server and is used to cool a plurality of servers. Certainly, the immersion water tank may also be used for other purposes, and a scenario in which a plurality of cooling unitsneed to be cooled may be used.

500 300 300 600 In the immersion water tank provided in some embodiments of the present disclosure, by means of the arrangements of the movable obstructing platesand the spring-back baffles, the height reduction of the overall liquid level caused during maintenance of a single node can be avoided, and by means of the design of the bottom spring-back baffles, an unnecessary liquid can be prevented from passing through a channel of a storage uniton which a node is not placed, such that not only the heat dissipation efficiency of the overall water tank can be improved, but also the dual effects of saving the liquid usage amount and reducing the operation and maintenance costs are further achieved.

1 FIG. 1 FIG. 1 FIG. 205 200 205 200 600 600 500 500 500 600 500 600 500 600 500 500 100 600 500 500 1 600 2 In some embodiments, as shown in, a plurality of limiting portionsare provided on a side wall of the tank bodyin the longitudinal direction thereof. Specifically, the limiting portionsmay be tracks which extend in the longitudinal direction of the tank body, and the tracks are located between adjacent storage unitsand are used for obstructing two adjacent storage units, and the obstructing platesare slidably connected to the tracks. Specifically, by means of the obstructing platesbeing detachably connected to the tracks, a movable design of the obstructing platesis achieved. Before a storage unitnode is to be maintained, the obstructing plateson two sides of the storage unitnode are first inserted into tracks reserved in the water tank, installation tracks of the obstructing platesneed to be provided in the water tank between the storage unitnodes, the obstructing platesshould be higher than the liquid level after the installation of the obstructing plates, and a cooling unitin the storage unitnode to be maintained is pulled out after the positioning of the obstructing platesis completed. In this case, due to the obstructing effect of the obstructing plates, the liquid level of other nodes that are in normal operation does not change, for example, the standard liquid level is Hin, and only the liquid level of the storage unitnode that is being maintained is reduced, for example, the reduced liquid level is Hin.

205 200 600 600 500 500 500 600 500 600 500 600 Alternatively, the limiting portionsmay be grooves which extend in the longitudinal direction of the tank body, the grooves are located between adjacent storage unitsand are used for obstructing two adjacent storage units, and the obstructing platesare slidably connected to the grooves. Specifically, by means of the obstructing platesbeing detachably connected to the grooves, a movable design of the obstructing platesis achieved. Before a storage unitnode is to be maintained, the obstructing plateson two sides of the storage unitnode are first inserted into grooves reserved in the water tank, and the grooves of the obstructing platesneed to be provided in the water tank between the storage unitnodes.

500 200 500 201 200 500 500 200 500 200 In some embodiments, in order to ensure that the height of the obstructing platesis greater than that of the cooling liquid in the tank body, and due to the liquid level may change when the water tank is in use, or the liquid level may be affected by the fluctuation of the liquid surface, and therefore the height of the obstructing platesis set to be greater than or equal to that of the cooling unit support platefrom the top of the tank body, that is, after the obstructing platesare installed in place, the top of the obstructing platesis flush with the top of the tank body, or the top of the obstructing platesis higher than the top of the tank body. Such an arrangement can avoid possible changes in the liquid level in the water tank, or the liquid level from being affected by the fluctuation of the liquid surface, further improving the reliability.

500 500 201 600 500 201 500 500 600 500 It should be noted that, when the obstructing platesare installed in place, the bottom of the obstructing platesshould abut against the cooling unit support plate, so as to reduce the entry of the cooling liquid into the corresponding storage unitthrough the gap between the bottom of the obstructing platesand the cooling unit support plate. Meanwhile, a sealing gasket should also be provided between the obstructing platesand the tracks, for example, a rubber layer may be provided on each track, or rubber layers may be provided on two sides of the obstructing plates, so as to reduce entry of the cooling liquid into the corresponding storage unitthrough the gap between the side faces of the obstructing platesand the tracks.

202 201 600 202 201 100 In some embodiments, a plurality of liquid inlet portionsare provided on the cooling unit support plateat a position corresponding to each storage unit. Specifically, the number of the liquid inlet portionsis preferably multiple, so as to ensure sufficient flow of the cooling liquid passing through the cooling unit support plate, thereby improving the circulation effect of the cooling liquid and ensuring the cooling effect of the cooling unitafter maintenance.

202 201 600 300 201 201 600 300 600 300 600 201 201 600 303 300 In some embodiments, the liquid inlet portionsare liquid inlet holes, and the liquid inlet holes are provided at the position on the cooling unit support plateclose to the center of the storage unit. Such an arrangement is used for ensuring a quick return flow of liquid after the spring-back baffleis away from the cooling unit support plate. In addition, the liquid inlet hole is provided at a position on the cooling unit support plateclose to the center of the storage unit, that is, the spring-back baffleblocks the liquid inlet hole at the relatively center of the storage unit, facilitating the application of force, improving the reliability of sealing the liquid inlet hole by the spring-back baffle, and preventing the cooling liquid from flowing into the storage unitthrough the liquid inlet holes on the cooling unit support plate. Meanwhile, the liquid inlet holes are provided at a position on the cooling unit support plateclose to the center of the storage unit, which can also be used for reserving a sufficient space for the installation of the pinsin the spring-back baffle. Preferably, the liquid inlet holes are circular holes, which is easy to process, can reduce the processing cost, has a small resistance to the cooling liquid, and facilitates the circulation of the cooling liquid.

201 202 201 600 201 201 600 201 600 201 600 201 201 100 In some embodiments, the cooling unit support plateis of an integral structure, and a plurality of liquid inlet portionsare provided on the cooling unit support plateat a position corresponding to each storage units; the cooling unit support platein the water tank is preferably of an integral structure, and a plurality of liquid inlet holes are provided on the cooling unit support plateat a position corresponding to each storage unit; certainly, a cooling unit support platemay also be separately provided at a position corresponding to each storage unit. In order to facilitate processing, preferably, a same cooling unit support plateis used in the water tank, and then liquid inlet holes are provided at a position corresponding to each storage unit. This selection not only facilitates processing, but also improves the strength and stability of the cooling unit support plate, and ensures the bearing effect of the cooling unit support platefor the cooling unit.

300 600 300 600 300 100 600 In some embodiments, the number of the spring-back bafflesis the same as that of the storage units, and the positions of the spring-back bafflesand the storage unitsare in one-to-one correspondence. Specifically, the spring-back bafflessatisfy the maintenance requirements for a cooling unitin a single storage unit.

300 600 300 200 In some embodiments, the spring-back baffleshave a size smaller than the cross-sectional size of the storage units, the spring-back bafflesonly need to satisfy the requirement of blocking the liquid inlet holes, and there is no need a large size, reducing the volume, and providing a sufficient space for the flow of the cooling liquid at an inner bottom of the tank body.

700 200 700 200 200 200 700 200 700 In some embodiments, a secondary water tankin communication with the tank bodyis further included. The secondary water tankcan supplement a cooling liquid for the tank body, specifically, with the volatilization of the cooling liquid in the tank body, the volume of the cooling liquid gradually decreases, and when the volume of the cooling liquid in the tank bodyis smaller than a target volume, the cooling liquid in the secondary water tankis added into the tank body. As the volatilization of the cooling liquid is slow, there is no need to store much cooling liquid in the secondary water tank, reducing the usage amount of the cooling liquid.

300 301 400 400 301 201 201 301 In some embodiments, the spring-back bafflecomprises a baffle bodyand elastic components, the elastic componentscan drive the baffle bodyto be closely attached to the cooling unit support plate, thereby blocking the liquid inlet holes on the cooling unit support plateby the baffle body.

400 301 100 201 400 301 201 100 201 301 400 Further, the elastic componentsare mounted on the side of the baffle bodyclose to the tank bottom; when the cooling unitis separated from the cooling unit support plate, the elastic componentscan push the baffle bodyto be attached to the cooling unit support plate; and when the cooling unitis close to the cooling unit support plate, the baffle bodycan be pushed to compress the elastic components.

400 301 200 301 400 301 400 301 201 301 201 400 301 201 301 400 301 400 301 201 301 201 301 201 400 301 200 That is to say, the elastic componentsare located between the baffle bodyand the tank bottom of the tank body, when the baffle bodyis forced to move towards the tank bottom, the elastic componentsare compressed, and when the baffle bodyis no longer forced, the elastic componentsare restored under the action of an elastic force, so as to push the baffle bodyto move towards a direction close to the cooling unit support plate, thereby achieving the purpose that the baffle bodyblocks the liquid inlet holes on the cooling unit support plate. Certainly, the elastic componentsmay also be provided between the baffle bodyand the cooling unit support plate, when the baffle bodyis forced to move towards the tank bottom, the elastic componentsare stretched, and when the baffle bodyis no longer forced, the elastic componentsare restored under the action of the elastic force, so as to push the baffle bodyto move towards a direction close to the cooling unit support plate, thereby achieving the purpose that the baffle bodyblocks the liquid inlet holes on the cooling unit support plate. Certainly, in order to ensure the blocking effect of the baffle bodyon the liquid inlet holes on the cooling unit support plate, it is preferable that the elastic componentsare located between the baffle bodyand the tank bottom of the tank body.

300 600 300 300 600 600 It should be noted that the number of the spring-back bafflesin the water tank is multiple, each storage unitnode is provided with one spring-back baffle, and the spring-back bafflesare used for a single storage unit, so as to block the liquid inlet holes of the single storage unit.

400 100 201 301 201 202 100 201 301 400 100 By means of the arrangement of the elastic components, the above arrangement ensures that when the cooling unitsare separated from the cooling unit support plate, the baffle bodycan be attached to the cooling unit support plate, achieving the blocking effect for the liquid inlet portions, and ensuring sealing reliability; and at the same time, when the cooling unitsare close to the cooling unit support plate, the baffle bodycan be pushed to compress the elastic components, achieving the buffering effect, so as to prevent the cooling unitsfrom colliding with the tank bottom and causing damage.

303 301 201 303 201 303 201 100 201 301 303 303 600 303 In some embodiments, pinsare provided on the side of the baffle bodyclose to the cooling unit support plate, and the pinspass through the cooling unit support plate. Specifically, a through hole for each pinto pass through is provided on the cooling unit support plate. When the cooling unitis close to the cooling unit support plate, the baffle bodyis pushed by the pinsto move towards the tank bottom. Further, the pinsand the through holes should be sealed to prevent the cooling liquid from entering the storage unitsthrough the gap between the pinsand the through holes.

303 301 100 201 301 303 301 301 Specifically, there are preferably two pins, which are respectively located at positions of the baffle bodyclose to left and right sides, and when the cooling unitis close to the cooling unit support plate, the baffle bodyis smoothly pushed by the pinsat two sides of the baffle bodyto move towards the tank bottom, thereby ensuring the stability of the movement of the baffle body.

303 301 201 303 303 201 303 100 201 301 303 Further, the pinson the baffle bodymay correspond to the positions of the liquid inlet holes of the cooling unit support plate, that is, each pinmay be provided in the center of the sealing gasket. In this way, there is no need to provide a through hole for the pinto pass through on the cooling unit support plate, and the liquid inlet hole is used as a through hole for the pinto pass through, thereby reducing the processing of a through hole. When the cooling unitis close to the cooling unit support plate, the baffle bodyis pushed to move towards the tank bottom by means of the pinat the position of the liquid inlet hole.

303 303 600 It should be noted that, in order to prevent the pinfrom affecting the liquid inlet hole, the cross-sectional size of the pinshould be obviously smaller than that of the liquid inlet hole, so as to ensure that the cooling liquid can flow into the storage unitthrough the liquid inlet hole smoothly.

100 201 201 201 100 201 301 100 100 201 301 100 301 100 201 201 100 201 301 600 In some embodiments, protrusions are provided on the side of the cooling unitclose to the cooling unit support plate, and the protrusions pass through the cooling unit support plate. Specifically, a through hole for each protrusion to pass through is provided on the cooling unit support plate, and when the cooling unitis close to the cooling unit support plate, the baffle bodyis pushed by the protrusions to move towards the tank bottom. Specifically, there are preferably two protrusions, which are respectively located at positions of the cooling unitclose to left and right sides, and when the cooling unitis close to the cooling unit support plate, the baffle bodyis smoothly pushed by the protrusions at two sides of the cooling unitto move towards the tank bottom, thereby ensuring the stability of the movement of the baffle body. Further, the protrusions on the cooling unitmay correspond to the positions of the liquid inlet holes of the cooling unit support plate. In this way, there is no need to provide a through hole for the protrusion to pass through on the cooling unit support plate, and the liquid inlet hole is used as a through hole for the protrusion to pass through, thereby reducing the processing of a through hole. When the cooling unitis close to the cooling unit support plate, the protrusion will pass through the liquid inlet hole, and the baffle bodyis pushed to move towards the tank bottom. It should also be noted that, in order to prevent the protrusion from affecting the liquid inlet hole, the cross-sectional size of the protrusion should be obviously smaller than that of the liquid inlet hole, so as to ensure that the cooling liquid can flow into the storage unitthrough the liquid inlet hole smoothly.

301 201 304 202 304 202 304 202 304 304 202 202 600 304 202 In some embodiments, the side of the baffle bodyclose to the cooling unit support plateis provided with sealing componentsfor blocking the liquid inlet portions, the positions of the sealing componentsand the liquid inlet portionsare in one-to-one correspondence, and the size of the sealing componentsmay be slightly larger than that of the liquid inlet portions, so as to ensure a good sealing effect. Preferably, in order to save the usage amount of the material of the sealing components, the sealing componentsare preferably sealing gaskets, and the size of the sealing gaskets is consistent with that of the liquid inlet portions; that is, the sealing gaskets is used to seal the periphery of the liquid inlet portions, so as to prevent the cooling liquid from entering the storage unitsalong the gap between the sealing componentsand the liquid inlet portions. Further, the material of the sealing gaskets may be replaced with rubber or other soft material.

The obstructing platesare required to be higher than the liquid level after installation, and then the server to be maintained is pulled out after the obstructing platesare positioned. In this case, due to the blocking of the obstructing plates, only the liquid level of the storage unitin which the server to be maintained is located is reduced, and the liquid level of other storage unitnodes that are in normal operation does not change. In addition, the design of a spring-back baffleat the bottom of the water tank can effectively prevent a liquid in a liquid inlet from continuously flowing into the unused node. Please refer tofor the operation mechanism of the spring-back baffle, when the server is not installed, the spring-back baffleis lifted by the bottom elastic componentsto block the liquid inlet holes, and when the server is installed, the spring-back bafflecan be pressed down by means of the structure of pinson two sides of the baffle bodyto open the liquid inlet holes, and the cooling liquid can flow smoothly into the storage unitsat this time. As shown in, the spring-back bafflecomprises a baffle body, pinsand sealing gaskets located above the baffle body, and elastic component positioning recesseslocated below the baffle body. The size of the sealing gaskets must be provided to match the liquid inlet holes of the cooling unit support plate, the main purpose being that after the server node is removed, the bottom plate is pushed up so that the flexible sealing gaskets achieve a better blocking effect on the liquid inlet holes. The bottom elastic component positioning recessesare mainly used to cooperate with the elastic componentsbelow, preventing the elastic componentsfrom being laterally displaced or bent when the baffle bodyis operated, and ensuring that the elastic componentscan actually operate in a straight up and down manner. Furthermore, it is necessary to provide elastic component clearance recessesbelow the bottom of the tank body, which are mainly used to provide sufficient storage spaces for the elastic componentsafter being compressed, so as to ensure that a liquid flow pathis unobstructed, and elastic component fixing pinsare further provided in the elastic component clearance recessfor fixing the elastic components, so that the elastic componentsare not deviated or even disconnected.

The immersion water tank has the following beneficial effects:

1. The Maintenance Manner of Existing Immersion Water Tank Servers is Improved

300 An important issue in the design of existing immersion water tanks is how to ensure that the same liquid level can be maintained while a server is being maintained, so that other servers that are in normal operation are not exposed to the risk of heat dissipation. With this design, not only can the liquid level be maintained, but the bottom spring-back bafflecan also play the role of a buffer when the server is repositioned to prevent damage caused by collision between the server and the bottom of the water tank.

2. The Usage Amount of the Working Cooling Liquid is Reduced

200 In the immersion water tank, regardless of the number of nodes to be maintained in the tank body, the amount of the cooling liquid used in the water tank can be controlled to be maintained at the same level as before the maintenance, without having to add more cooling liquid to be filled to maintain the same liquid level due to the number of nodes to be maintained.

3. The Operation Efficiency of the Water Tank is Improved

300 200 600 600 By means of the design of the spring-back bafflesat the bottom of the tank body, the liquid inlet holes at the unused storage unitnode are closed in a timely manner, thereby preventing unnecessary liquid from flowing into the unused storage unitnode, and achieving the effect of improving the operation efficiency of the water tank.
